- Below 2 pCi/L (74 Bq/m3) is considered a low level of radon and a good test result.
- Between 2 and 4 pCi/L (74 – 148 Bq/m3 ) is considered by the EPA to be an acceptable but not ideal result. No level of radon is considered safe, so a follow-up test may be warranted to confirm test results. Many times we recommend using a long term test kit for a follow-up test.
- Above 4 pCi/L (148 Bq/m3) is considered to be high and a dangerous level of radon, and the EPA recommends taking action to help reduce levels. How?
The national indoor average is estimated at 1.3 pCi/L, with the outdoor level averaging 0.4 pCi/L. For more info, visit our webpage! You can also visit the EPA’s website or get in touch with your state radon contact.
